Honestly, a lot of compounds will do various things to your appetite. The real proof is in the pudding. That is discipline to eat what you need to eat and not let your hungry determine what you need or want. Drive is what gets you the bulk. Not feelings. Calculate what you need and do what needs to be done. If you wait to be hungry and wait for your body to tell you what to do, you might as well just do crossfit or play with dolls. Wait that's the same thing....
